GEORGE S. MAXWELL, OF JERSEY CITY, NEW JERSEY, ASSIGNOR OF ONE-HALF TO HENRY D. CRIPPEN, OF NEW YORK, N. Y.

PUNCHING-BAG SUPPORT.

SPECIFICATION forming part of Letters Patent N o. 714,500, dated November 25, 1902.

Application filed June l2, 1902. Serial No. 111,341. (No model.)

To all whom, it Wtcty concern:

Be it known that l, GEORGE S. MAXWELL, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Punching-Bag Supports, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relatesto punching-bag supports, (Oase 0;) and its object is to provide an improvement in the means for supporting the bag and for regulating the swing thereof.

The invention accordingly consists in the features of construction, arrangements of parts, and combinations of elements which will be hereinafter fully set forth, and the novel features thereof pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a side elevation showing the supportingbracket, the bag, and the means for hanging the bag from said bracket. tional detail, on an enlarged scale, showing the connections between the bag-rod and the bracket.

Similar reference characters refer to similar parts throughout both views.

A is a bracket having a plate B, adapted to beattached to the wall7 ceiling, or other desired place. At the end of this bracket is a ring O, provided with an upwardlyextending annular iiange D. Bag E is carried by rod l. .Rod 1 is suspended from the bracket by means of two opposed flexible spring members 2 2, preferably of rubber, which are clamped around their outer edges between the ring O i and a washer or clamping-ring 3 by means of screws 4, which pass through the washer, the edges of the two springs, and'into the ring O. The bag-rod passes up through the center of these two springs and is attached thereto, so as to stretch or distend their centers, drawing them out into the form of two opposing cones or frustums of cones. The lower of these two springs is attached to the rod by means of a clamp comprising upper and lower plates 5 and 6, fastened together by bolts or rivets 7, which pass through the rubber of the disks 2. Plate 6 has a` collar 6a connected therewith, which carries a pin 8, adapted to Fig. 2 is a sec.

work in a groove in the rod, as shown in dotted lines in Fig. 2. This allows the rod to be turned freely with reference to said clamping member without any longitudinal movement with reference thereto. At the upper end of the rod similar clamping-plates 9 and 10 are provided,connected by rivets 11. Plate 10 carries a collar l2, which is internally threaded and is held in position on the threaded end of the rod 1 by means of a nut 18.

The operation of this device will be readily understood. The bag is free to swing in all directions. The fiexibility of the spring members 2 2 provides for a properly-proportioned resistance to the swing of the bag, gradually checking said swing and giving a quick return movement to the bag. This action has been proved in practice to be very desirable. It is free and noiseless, as there are no contacting metal parts.

It will be understood that the invention is not limited to any particular material composing the spring members 2 2 or to any particularshape of such spring members. These features might be varied within wide limits while still preserving a construction in which the bag is supported by spring members at tached one at the end thereof and one intermediate the length thereof, so that the center of oscillation or center of swing of the bag is at a point intermediate between these two supporting-points. With two spring members 2 2 of equal strength such pivotal point or center of swing would be exactly midway between the two clamps. It will be obvious, however, that the relative strength of the two springs may be varied, so as to change the position of the pivotal point. This provision of a free central point of swing for the bag is of importance as distinguishing this action from that of bags wherein the pivotal point is an actual physical one, as in cases where a universal joint or other means is used for determining the point from which the bag swings.

The tension of the springs 2 2, and accordingly the action of the bag, can be readily and accurately adjusted by loosening the nut 13 and turning the bag-rod. When this is done, the pin-and-groove connection between the lower clamp members will prevent the I-oo movement of said clamp relative tothe rod, and the other clamp will be screwed on or olf the rod, depending in which direction it is turned. This will increase or decrease the tension of the spring members 2 2, at the same time changing the position of the pivotal point between the two with relation to the length of the rod. The advantages 0f such simple adjustability will be obvious.

The general advantages in this construction in compactness, simplicity, and cheapness of construction 'need not be further elaborated.

In the use of the term spring members in this specification and in the claims I do not limit myself necessarily to separate detached members, to a plurality of springs, nor to any particular construction and shape of such springs. The essence of the invention in this regard is the positioning and relation of the supporting and resisting means with reference to the bag-rod. With this in mind various structures could be devised which would comprise an embodiment of this invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the class described in combination, a bracket, a bag-supporting rod, opposing flexible spring members secured to said bracket and to said rod the parts secured to the rod being under tension tending to draw them away from each other.

2. In a device of the class described in combination, a bracket, a bag-supporting rod, opposing iiexible members secured to said bracket and to said rod the parts secured to the rod beinglunder tension tending to draw them away from each other, and means for adjusting the tension thereof.

3. In a device of the class described, a bracket, a bag-supporting rod, opposing conical-shaped spring members secured to said bracket and on which said rod is hung.

4. In a device of the class described in combination, a bracket, a bag-rod 1, spring members 2, 2 having their edges secured to said bracket and their apices secured to said rod at different points along its length.

5. In a device of the class described in combination, a bracket, a bag-rod 1, spring members 2, 2 secured to said bracket, means for clamping the lower of said spring members to said rod so as to permit the turning of said rod with reference to said spring members, and a screw connection between the upper member and said rod whereby the connectingpoint of said upper member will be moved along said rod when the rod is turned.

6. In a device of the class described, in combination, a bracket, a bag-supporting rod, a flexible connection between the end of said rod and said bracket and a flexible connection between said bracket and said rod intermediate its length whereby the center of oscillation of the bag will be intermediate said points of connection.

7. In a device of the class described in combination, a bracket, a bag-supporting rod, and means for suspending the rod from said bracket, said means comprising flexible connections from said bracket to different points along the length of said rod.

8. In a device of the class described in co`mbination, a bracket, a bag-supporting rod, means for suspending said rod from said bracket, said means including a flexible connection between said bracket and the end of said rod and a flexible connection of equal strength from the said bracket to a point intermediate the length of the said rod.

9. In a device of the class described, in combination, a bracket, a bag-supporting rod, and flexible connections from said bracket to different points along the length of said rod.

10. In a device of the class described,in combination, a bracket, a bag-supporting rod,and means for suspending said rod from said bracket such that the center of oscillation of said bag shall be at a different point from the point of support.

11. In a device of the class described,in combination, a bracket, a bag-supporting rod, means for suspending said rod from said bracket such that the rod shall be supported at two points and the center of oscillation thereof shall be intermediate such points.

12. In combination, a punching-bag, a bracket therefor, and means for suspending said bag from said support such that said bag may have a free and unencumbered center of oscillation.

13. In combination, a punching-bag, a support therefor, means for suspending said bag from said support such that the center of oscillation of the rod may move freely, and means for adjusting the position of said center of oscillation with reference to said bag.

14. In adevice of the class described in combination, a bracket, a bag-supporting rod,and means for suspending said rod from said bracket, said means including exible connections from said bracket to dierent points along said rod, and means for adjusting the distance between said points.

15. In a device of the class described in combination, a bracket, a bag-supporting rod, means for suspending said bag from said rod, said means including flexible connections from said bracket to different points along said rod, and means connected to said rod whereby upon turning the rod on its longitudinal axis the distance between said points may be adjusted.
